  • Patent number: 11446916
    Abstract: A method to manufacture an elastic laminate is disclosed. Thermoplastic Elastomeric Material (TEM) is selected from a polymer supply and fed into an extruder. The TEM film is extruded by the extruder by passing the TEM polymer through an extrusion die head to form a TEM film layer on a carrier web provided by a carrier supply. The TEM film layer is allowed to solidify on the carrier web, thereby forming a first laminate. The first laminate is stored in a first storage prior to being delivered to a delamination unit, which delaminates the first laminate by separating the TEM layer from the carrier web. The delaminated TEM layer is stretched at least in its Machine Direction (MD) in a stretching station via a plurality of web guide means. The stretched TEM layer is positioned between a first envelope web and optionally a second envelope web prior to being delivered to a bonding unit, which connects them to form a second bonded laminate.

  • Patent number: 9453322
    Abstract: A cellular confinement system for soil, sand or other filler material comprises a number of sub-assemblies each made up of a plurality of interconnected open cells of fabric material. The sub-assemblies are stackable one on top of the other to provide a structure having at least one generally vertical side or end wall.

  • Patent number: 8465611
    Abstract: A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline.
